Queensland unionists tell Abbott he's next

Queensland unionists have one message for Tony Abbott: "We are coming for you."

They gathered outside Parliament House in Brisbane on Wednesday to celebrate Labor's return to power and send a warning to the coalition in Canberra that it will be next.

The rally was part of a nationwide day of action, flagged by organisers as the first step in a new campaign to dethrone the federal government.

"Isn't this a great day to be out telling Tony Abbott and the federal Liberals that they are next?" Queensland Council of Unions assistant general secretary Ros McLennan said.

"We've done it in South Australia, we've done it in Victoria and we've done it in Queensland.

"We're going to take it all the way to Canberra."

As she took to the stage, triumphant Labor leader Annastacia Palaszczuk promised to stand up to the Abbott government if any changes to the minimum wage or penalty rates were made as a result of a productivity commission inquiry into the industrial relations system.

"We do not want any changes to penalty rates in this state (and) we will not dismantle the minimum wage," Ms Palaszczuk told the roaring crowd.

"We will stand up to Tony Abbott. And I will fight with you every step of the way."

After her address, she joined in with organisers' plans to snap a "solidarity selfie" to take the rally online, with protesters lining up to take a picture with the new premier.

Australian Council of Trade Unions president Ged Kearney says the selfies will eventually be transformed into a mural.

It followed chants of "One, two, three-and-a-bit, Tony Abbott is full of s***" from the crowd, with an oversize prime minister even taking to the stage with a Work Choices zombie in tow.

About 2000 turned out at the Brisbane rally.

Mr Kearney said the former Newman government had learnt the hard way there was no political benefit to attacking the union movement.

"This time three years ago, we had 78 LNP members up there," he said.

"There's now only 42 left."
